LINE-MAKING ATTACHMENT FOR 'rxrnwnrrme-uacnmns.

Specification of Letters Patent.

Patented Nov. 22, 1921.

Application filed March 27, 1920. Serial No. 869,207.

To all whom it may concern:

Be it known that I, RICARDO GUERRERO PEREIRA, a citizen of the Republicof Chile, and a resident of Valparaiso, Chile, South America,haveinvented a new and Improved Line-Making Attachment for Typewriting-Machines, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improved line-makingattachment for typewriting machines, arranged to permit the user toquickly and accurately produce horizontal or vertical lines orcombinations of the same, and such as. are used in making outstatements, diagrams, invoices and other typewritten matter.

Another object is to permit of readily applying the attachment tovarious types of typewriting machines without requiring any or, at theutmost, but slight changes in the general construction of thetypewriting machines.

Another object is to permit of drawing successively a plurality ofvertical lines spaced desired distances apart and without requiringshifting of the carriage.

With these and other objects in view, the invention consists of certainnovel features of construction as hereinafter shown and described andthen specifically pointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming a art of this specification, in whichsimilar characters. of reference indicate correspondin parts in all theviews.

Figure 1 is a p an'view of the improved line-making attachment asapplied to an Underwood typewriting machine;

Fig. 2 is an enlarged plan view of the line-making attachment;

Fig. 3 is a cross section of the same on the line 3-3 of Fig. 2;

Fig. 4 is a sectional front elevation of the same on the line 44 of Fig.2; and

Fig. 5 is a sectional plan view of the attaching clip in position on thetop bar guide of the typewritmg machine.

he improved line-making attachment for a typewriting machine is arrangedin front of the cylinder or roller platen 10, on which.

is held the paper 11 adapted to receive the desired typewritten matter,and horizontal .and vertical lines 12 and 13 adapted to be produced by aline-makin attachment, as hereinafter more fully exp ained. It isunderstood that the platen 10' is mounted to turn in the usual manner inthe carriage 14.- adapted to travel sidewise from right to left, andfrom left to right, as is well known. As shown in Figs. 1, 3, 4 and 5,the linemaking attachment is mounted on a station ary type bar guide 15of the typewriting machine, and for this purpose use is made of anapproximately inverted U-shaped spring clip 20 having clamping jaws 21clampingly engaging the outer sides of the type bar guide. The springclip 20 is sufficiently high to permit the passage of the type end ofthe type bar making an impression at the time on the paper 11, and thetop of the clip 20 is attached to the under side of a guideway 25ranging sidewise approximately parallel to the cylinder or roller platen10. In the guideway 25 is mounted to slide sidewise a slide 26 having anupturned threaded lug 27 in which screws an adjusting screw 28 mountedto turn in the upturned lug 29 forming an integral part of one end ofthe guideway 25. The screw 28 is provided with a suitable knurled head30 to permit the user to conveniently turn the screw 28 with a view toshift the slide 26 sidewise, either from the right .to the left or fromthe left to the right according to the direction in which the screw 28is turned at the time. The slide 26 is provided with a post 35 on whichis secured a tube 36 slightl inclined downwardly and rearwardly, wit

its axis approximately intersecting the axis of the cylinder or rollerplaten 10. In the tube 36 is mounted to slide transversely a holder 4:0for carrying a pen, pencil or other writing implement 41 adapted to drawthe horizontal lines 12 or the vertical lines 13 on the operator pushingthe holder 40 rearwardly in the tube 36 to engage the writin implementwith the paper 11. Now it wi be noticed that when the writing implement41 is in contact with the paper 11, and the carriage 14 of thetypewriter is shifted from the left to the right or from the ri ht tothe left, then a horizontal line 12 is rawn on the paper 11, and whenthe writing 1mplement 41 is in contact with the paper 11 and a turningmovement is given to the roller or cylinder platen 10 then a verticalline 13 is drawn on the paper 11.

The writing'implement holder 40 is preferably in the form of a shell 42mounted to slide in the tube 36 and pressed on by a spring 43 resting atone end against the upper end of the tube 36 and abutting with its otherend on a head 44 attached to the outer end. of the shell 42. A stop pin45 is attached to the shell 42 and extends through a slot 46 formed inthe top of the tube 36. to limit the movement of the shell 42 in thetube 36. It is understood that the spring 43 normally holds the writingimplement 41 in retracted position, that is, a short distance away fromthe peripheral face of the roller or cylinder platen 10. The shell 42 isprovided at its forward end with jaws 50 clampingly engaging the writingimplement 41, and the jaws 50 are held 1n clamping position by the usualjaw-closing and opening member 51 screwing on the threaded portion 52 ofthe shell 42. The writing implement 41 may be in the form of a leadpencil or an ink point.

It is understood that when the operator desires to make a horizontalline 12 on the paper 11 then the operator pushes on the head 44 to movethe writing implement 41 in contact with the paper 11, and then theoperator shifts the carriage 14 either to the right or to the left todraw a horizontal line on the paper 11 at the desired place. When thishas been done, the operator releases the pressure on the head 44 toallow the spring 43 to retract the holder 40. When it is desired to drawa vertical line, the operator pushes the head 44 to engage the writingimplement 41 with the paper 11 at the desired point to which thecarriage 14 was shifted, and then the operator turns the roller orcylinder platen 10 to correspondingly move the paper 11 whereby avertical line is drawn on the paper by the writing implement 41. lVhenit is desired to draw another vertical line alongside but spaced fromthe first made vertical line and without shifting the carriage 14, it isonly necessary for the operator to turn the screw 28 to shift the slide26 and with it the tube 36 and the holder 40 to the right or to the leftthe desired distance to be had between the line made and the next lineto be made. The operator then pushes the tube holder the same aspreviously explained and then turns the platen 10 whereby a secondvertical line is drawn on the paper 11 either to the right or to theleft of the first line according to the direction in which the slide 26is shifted.

From the foregoing it will be seen that the line-making attachment forthe typewriting machine is very simple and durable in construction andcan be readily applied to a typewriting machine without requiringchanges in the construction thereof.

Instead of mounting the line-making attachment on the stationary typebar guide 15, it may be attached to a lever actuated by a special keywhich when pressed moves the device into the desired position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1.
